(Invited) Hot Electron Generation and Photocatalysis with Plasmonic Nanocrystals and Metastructures

Abstract

The generation of energetic (hot) electrons and the photoheating are intrinsic properties of any optically excited plasmonic nanocrystal [1,2]. In addition, high-energy hot electrons and phototemperature contribute to the kinetic processes observed in plasmonic photodetectors, colloidal nanocrystals, and metastructures [1,2]. In this talk, we will focus on the theory of hot electron generation and present related applications for plasmonic photochemistry and plasmonic photocatalysis [3,4,5,6]. [1] L. Chang, L. V.
